Have the same issue. It seems to be an 7th Problem with the new Windows Build 1809. Before the Windows Update i could play the game.

It doesn't matter how many mods u have activated or not. U got the problem with just one Mod activated. So, the problem is the program itself. Maybe the creator can patch it.

I can start the game directly by clicking the ff7.exe or the ff7_mo.exe without the 7th program. That works, but, u know, than are no mods active.

I am using now an workaround and don't use the 7th program anymore. Use the tool to unpack all your IRO Files to a location and select manual all of the mods and move the directories to the correct place in the game folder. Works. For some Mods, u need the lgptools.exe to edit the current game files. If u have just png files in the mod folder, put them to mods\Texture\

Hmm... This smells like some sort of security feature Microsoft added to protect against injection attacks. Hopefully, this doesn't require too substantial a reworking of 7H's code in order to get it working again.

@PoisonJohnnyI think I may have found a fix if you could give it a try and let us know please.

Right click the 7thheaven and set and set the compatibility to run as as administrator. apply and close.Then find the FF7 exe you are using eg.. ff7_bc right click and set compatibility to run in 640x480. Don't worry the opengl plugin will override this anyway.Next go back into 7thheaven and try launching the game.This seems to have worked for me going to test on my tab that had same problem.
